46  * The Aironet 4500/4800 series cards come in PCMCIA, ISA and PCI form.
47  * This driver supports all three device types (PCI devices are supported
48  * through an extra PCI shim: /sys/dev/an/if_an_pci.c). ISA devices can be
49  * supported either using hard-coded IO port/IRQ settings or via Plug
50  * and Play. The 4500 series devices support 1Mbps and 2Mbps data rates.
51  * The 4800 devices support 1, 2, 5.5 and 11Mbps rates.
52  *
53  * Like the WaveLAN/IEEE cards, the Aironet NICs are all essentially
54  * PCMCIA devices. The ISA and PCI cards are a combination of a PCMCIA
55  * device and a PCMCIA to ISA or PCMCIA to PCI adapter card. There are
56  * a couple of important differences though:
57  *
58  * - Lucent ISA card looks to the host like a PCMCIA controller with
59  *   a PCMCIA WaveLAN card inserted. This means that even desktop
60  *   machines need to be configured with PCMCIA support in order to
61  *   use WaveLAN/IEEE ISA cards. The Aironet cards on the other hand
62  *   actually look like normal ISA and PCI devices to the host, so
63  *   no PCMCIA controller support is needed
64  *
65  * The latter point results in a small gotcha. The Aironet PCMCIA
66  * cards can be configured for one of two operating modes depending
67  * on how the Vpp1 and Vpp2 programming voltages are set when the
68  * card is activated. In order to put the card in proper PCMCIA
69  * operation (where the CIS table is visible and the interface is
70  * programmed for PCMCIA operation), both Vpp1 and Vpp2 have to be
71  * set to 5 volts. FreeBSD by default doesn't set the Vpp voltages,
72  * which leaves the card in ISA/PCI mode, which prevents it from
73  * being activated as an PCMCIA device.
74  *
75  * Note that some PCMCIA controller software packages for Windows NT
76  * fail to set the voltages as well.
77  *
78  * The Aironet devices can operate in both station mode and access point
79  * mode. Typically, when programmed for station mode, the card can be set
80  * to automatically perform encapsulation/decapsulation of Ethernet II
81  * and 802.3 frames within 802.11 frames so that the host doesn't have
82  * to do it itself. This driver doesn't program the card that way: the
83  * driver handles all of the encapsulation/decapsulation itself.
